I was hoping that we could do it with macros, just as the integer
overflow tests are done with macros. The advantage of mac

While we're on the topic of C's arithmetic deficiencies, how about if
we also add a macro for safe and portable comparison?
Something like "ARITH_COMPARE (A, OP, B)" to compare A and B
numerically rather than using C's rules. So, for example,
ARITH_COMPARE (-1, <, sizeof "x") would return true ev
